Patents by Inventor Chris Fleming

Chris Fleming has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Recycling of solids in oxidative pressure leaching of metals using halide ions
    Patent number: 9039806
    Abstract: The invention provides a recycling step in an oxidative pressure leaching process for recovery of metals using halide ions, in which a portion of the leached solids are recycled back to the feed to the autoclave, to allow two or more passes through the high temperature leaching step.
    Type: Grant
    Filed: May 11, 2007
    Date of Patent: May 26, 2015
    Assignee: International PGM Technologies
    Inventors: David B. Dreisinger, Chris A. Fleming
  • T-structure invasive cleavage assays, consistent nucleic acid dispensing, and low level target nucleic acid detection
    Patent number: 8354232
    Abstract: The present invention relates to systems, methods and kits for low-level detection of nucleic acids, detecting at least two different viral sequences in a single reaction vessel, and increasing the dynamic range of detection of a viral target nucleic acid in a sample. The present invention also relates to T-structure invasive cleavage assays, as well as T-structure related target dependent non-target amplification methods and compositions. The present invention further relates to methods, compositions, devices and systems for consistent nucleic acid dispensing onto surfaces.
